Here's a simple method for capturing 3-d images of the earth from the live streaming video from the ISS. The method does rely on you being able to cross or uncross your eyes to obtain a single image from two.

The cross eye method.

Place the 2 images at sensible viewing distance with dark, uncluttered background. these should be side by side with edges parallel.

Cross your eyes as if you are looking at the end of your nose.

Slowly concentrate your brain on the confusion of images of the stereo pair.

Gradually uncross your eyes until your brain sees 3 distinct images.

Move your eyes and head until the centre image of the three is a single combined as one.

Then use your brain to decipher the 3D.

If you're that way inclined you can try the alternative stare straight ahead method (I cannot do it!)
